No alert is triggered in the following conditions:
– In the presence of non-moving objects (parked
vehicles, barriers, street lamps, road signs, etc.).
– Oncoming traffic.
– Driving on a winding road or a sharp corner.
– When overtaking or being overtaken by a very
long vehicle (lorry, bus, etc.) that is detected
in the rear blind spot but is also present in the
driver’s front field of vision.
– When overtaking quickly.
– In very heavy traffic: vehicles detected in
front and behind are confused with a lorry or a
stationary object.
Malfunction
In the event of a malfunction, this
warning lamp flashes for a few
moments in the instrument panel, accompanied
by the Service warning lamp coming on and the
display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot
angle is interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on the
front and rear bumpers with adhesive labels
or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance
The system signals the presence of obstacles
within the sensors’ detection zone.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
